the rbc roller cam follower advantage rbc roller cam follower the latest design and technology innovations patented rbc roller double row cylindrical roller cam followers represent the most effective cam follower technology available they are superior to needle roller cam followers in every way lubed for life higher load capacity higher speed rating and longer service life outer ring roller guidance rbc roller cam follower center thrust ring roller guidance dual row cylindrical rollers contacting lip seals these seals make contact only with the stud ground diameter therefore maximizing seal life they are not subject to thrust load against unground surfaces their sole function is to provide a secure seal for the retention of lubricant and exclusion of contaminants large diameter rollers carry high loads higher dynamic capacity results in greater fatigue life ­ greatly prolonging cam follower service life center thrust ring a unique element of the rbc roller design the center thrust ring aids in roller guidance and sustains thrust loads generated by cam follower misalignment available only in rbc s patented design precise roller guidance rbc roller cam followers typically run up to 50° f cooler due to accurate roller travel cylindrical rollers are guided by both the center thrust ring and internal shoulders of the outer ring large grease reservoir area between the roller paths is fully charged with up to 4 times more grease than like-sized needle roller cam followers this additional grease helps to ensure lubed for life performance eliminates the need for periodic relubrication 4
